The Krishnapuram Palace was built in the 18th century during the sovereignty of Marthanda Varma. The krishnapuram palace displays the typical Kerala style of architecture by way of its gable roofs, charmar windows and narrow corridors. There is a museum of antique sculptures, paintings and bronze articles in the palace. There is a large mural called Gajendra Moksha (supposed to be the largest mural in Kerala or among kerala murals) on the western end of the ground floor. The krishnapuram palace pool is also wel-known. The palace is situated 47km from Alappuaha at a place called Kayamkulam and it is on the way to Kollam.
